MOTOR FOR CULINARY BEATERS, MIXERS, 80C.

SPECIFICATION forming part of Letters Patent No. 403,502, dated May 21, 1889.

Application filed May ll, 1888, Serial No. 273,615. (No model.)

To all whom t may concern:

Be it known that I, EDWIN BALTZLEY, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Motors for Culinary Beaters, Mixers, the.; and I do declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to devices for mixing, kneading, creaming, and beating, and has for its object the provision of a base or support for the vessel which will have a combined rotary and reciprocatory motion,where by every part of the vessel will be brought under the action of the beater, which is yielding or flexible, so as normally to fill the vessel when the center of the vessel comes nearly or directly opposite the center of the beater. Now, when the vessel travels back and forth within certain limits, which are adjustable, the beater will be crowded against the side of the vessel with a greater or less degree of tension; but as the vessel rotates simultaneously with its reciprocating motion its position is constantly changing relatively to the beater. Thus it will be understood that each and every side of the vessel will come in contact with or be crowded against the beater. The base rotates in the same direction whichever way it is traveling.

The improvement consists of the novel features hereinafter more fully described and claimed, and shown in the accompanying drawings, in which- Figure l is a side view, parts being broken away, of a device embodying my invention; Fig. 2, a front view, parts heing broken away, of the device; Fig. 3, a top plan view, parts being broken away, of the base or support;

Fig. 4, a vertical section about on the line Z tappets; Fig. 7, a perspective View of the arm which is connected with the shipper-lever, showing the means for connecting the tappetadjusting screw or rod therewith.

The bed A of the device is provided with ways or tracks a, on which the stand or table B is mounted and guided in its reciprocating' movements, and has side sockets, a', in which are fitted the lower ends of the standards C, which are bolted therein. The cap or cross piece D, that unites the upper ends of the standards, supports the beater adjusting and driving devices. The beater E, of ordinary construction and adapted to contract and eX- pand in its circumferential length, is secured to the lower end of the shaft e, which has its upper end connected with the rack-bar F. The pinion f, meshing with the rack-bar F and keyed to a shaft controlled by the handwheel F', serves to move the rack-bar vertically and elevate and lower the beater.

E2 is a locking device, of ordinary construction, to hold the hand-wheel against movement when the beater is adjusted to the propel' position. The transverse shaft G, having band-pulleys G on its outer end and bevelpinion g on its inner end, which is in mesh with the bevel-pinion c', through which the shaft e moves, transmits motion to the beater from the shaft I-I through the endless belt g and the speed-cone g2 on the outer end ofthe shaft H. The bevel-pinion e', j ournaled in the cross-piece D and having the shaft e, having an endwise or vertical movement through the said pinion, is caused to revolve with the same by any wellknown means-as by a feather-and-spline connection; or the shaft may be angular in cross-section and the opening in the pinion of corresponding shape, as will be readily understood.

The shaft I-I, j ournaled transversely of the bed in suitable bearings, is provided at the end opposite the speed-cone g2 with a bandpulley, h, and between its ends with two idlepinions, h and h2, having half-clutches on their opposing ends, which are adapted to be engaged by corresponding half-clutches on the ends of the clutch-sleeve I, which is mounted on the shaft H between the said pinions h and h2 and keyed by a feather-andspline connection to revolve with the shaft,

but free to move thereon between the pin.

ions to engage with the one or the other, as may be required. The feed-screw J, j ournaled at its ends, is provided at its inner end with the pinion j, which is in mesh with the pinions h and h2 and passes through a nut, j, secured to the under side of the table B.

The shipper-lever K, having a pin, k, at one end, which iits in the annular groove i in the clutch-sleeve I, is mounted at its outer end on the vertical stud K so as to move therewith. The lower end of this stud K has the arm L secured thereto, which extends at right angles to the shipper-lever K.. The weighted lever M, journaled to operate in a vertical plane, has its lower end extended through a slot or opening, Z, in the arm L, and its upper end provided with the weight m, which is ad' land h2.

The tappet-rod N, having bearings in the bed and in the block Z on the arm L, is provided with a right and left thread on its outer portion, on which the tappets n and n are mounted, and has a crank, N, on its outer end for turning it and adjusting the tappets closer together or farther apart to regulate the travel of the table B. This rod is adapted to move longitudinally and carry with it the arm L. The ends of the tappets are extended and work between the plate O and the bed, which guide them in their movement and prevent them being carried around with the rod N when it is rotated to adjust the tappets.

The stop P, projecting from the table B and extending within the path of the tappets, en-

gages with each tappet alternately and moves the rod N in the direction of its length, and

shifts the arm L and lever K, and moves the clutch-sleeve from one to the other pinion, thus changing the direction of motion of the feed-screwy J from right to left, and vice versa.

'i If the shipper-lever K were changed solelyT with the pinion quickly.

The turn-table Q, mounted on the table B and adapted to rotate thereon, is held thereon by the bolt q. The central enlargement, q', ofthe turn-table fits within the depression b of the table B. The two pawls R, arranged diametrically opposite to each other and actingon opposite sides of the turn-table, have two heads, r, each adapted to engage with the teeth q2', formed on the periphery of the turntable Q.v The pawls are pivoted at opposite ends relative to each other, and one only acts on the turn-table at a time, and each of the pawls is held in engagement with the turntable by a spring, S, coiled about the pivotal support of the pawl and having its ends extended, one end of the spring bearing against the standard and the other end of the spring bearing against the pin r, depending from the -pawl R.

The table B is mounted on rollers h', which travel on the ways a. These rollersare held between pairs of lugs depending from the table.

In practice the vessel T, containing the substance to be treated, is placed on the turntable, and the beater is lowered to the requisite position by the rack-bar F, pinion f, and hand-wheel F. l

Motion is imparted to the device by applying power to the band-wheel h, which drives the shaft H, the beater E, through the means hereinbefore described, and the feed-screw J, through the clutch-sleeve K, oneof the pinions, h '71.2, and the pinion j. The motion of the screw impels the support in one or theV other direction, according to the direction of the motion of the said screw. When the table nearly reaches the limit of its travel, the stop P thereof engages with one of the tappets and effects a longitudinal movement of the rod N, which movement is accelerated by the weighted lever M, as hereinbefore mentioned, and shifts the clutch-sleeve l from oneto the other of the pinions and reverses the motion of the screw, and consequently the direction of travel of the table, until said stop engages with the other tappet, when the motion of the screw and table will againbe reversed, and so on, as will be readily understood. During the reciprocating movement of the table one of the pawls will engage with the teeth q2 of the turn-table and rotate it, the other pawl lat the same time riding over the said teeth.

Now, when the motion of the table is re: versed, the pawl previously idlel will engage with the teeth and continue to rotate the table and the pawl previously active will now, be idle. Thus the pawls act alternately on the turn-table and eifect a contir uous rot-ary movement thereof. When the travel of the table is considerable, one head of the pawl will be thrown out of engagement with the teeth and the other head will be brought in VI OO IIS Having thus described my invention, whatl u claim, and desire to secure by Letters Patent, 1sA l. The combinatiomwith the bed, the table, means for reciprocating the table on the bed, and the shipperdever, of the tappet=rod hav= ing a right and a left thread, journaled in the said bed and adapted to have a longi tudinal and a rotary movement, the inner end of the rod being in connection with the shipper-lever, the tappets mounted on the said rod and moved to and from each other by rotating the rod, and means, as the crank N, for rotating the said tappet-rod, substantially as and for the purpose specified.
